    Translation - Japanese: FRで+B入力できるってご存じ?- Community Translated (JA)



    Generally to input higher voltage than Vcc of CPU to port is not guaranteed. But +12 voltage for automotive can be inputted to port directly by restricting current.
    Please confirm detailed information of current restriction value and etc. for this specification with datasheet.


    +B Input (individual corresponding)
    +B input port with external resister (for current control)
